Study on the influence of different menu sizes on the operation performance of touch screen

The key size of the touchscreen menu will significantly affect the user’s operation experience and task completion performance. This paper explores the influence of different shortcut menu sizes on users’ operation performance in the touch-screen application situations with two tilting angles $$(6.6^{\circ }\,\hbox {and}\, 18^{\circ })$$. The results show that the tilt angles of the two display screens have no significant influence on the response time of operators and the change trend of menu size. When the shortcut menu size is less than $$2.5\times 2.5\,\hbox {cm}$$, the operator’s response time increases significantly with the reduction of shortcut menu size. When the shortcut menu size is more than $$2.5\times 2.5\,\hbox {cm}$$, the increase of size has no significant impact on the operator’s response time. The shortcut menu recommends sizes between $$2.0\times 2.0\,\hbox {cm}$$ and $$2.5\times 2.5\,\hbox {cm}$$, with $$2.25\times 2.25\,\hbox {cm}$$ being a key size value.
